Electric clippers



April 10, 1956 c. D. GUENTHER ELECTRIC CLIPPERS Filed Feb. l6, 1955 II I H mm INVENTOR Chas/er 0. Guenl/zer United States Patent 2,741,026 ELECTRIC CLIPPERS Chester D. Guenther, Dayton, Ohio Application February 16, 1955, Serial No. 488,467

i 3 Claims. c1. 30-210 This invention relates to electric hair clippers.

It has been the practice heretofore to clip hair by moving the comb upward and the clipper from right to left along the comb or left to right (depending on righthanded or lefthanded operators). Thus, the actual hair cutting was accomplished in only one direction.

It is accordingly a principal object of the present invention to provide an improved electric hair clipper wherein, as the comb is moved upwardly, the clipper may be moved from right to left or left toright, clipping ofi the hair in both directions.

It is another object of the present invention to provide an improved electric clipper having a double ended cutting head which provides a convex operating surface, enabling it to be adjusted to varying angles of operation, offering increased flexibility of application thereof for more precise hair trim and cutting irrespective of the contour of the head being trimmed.

It is another object of the present invention to provide an electric hair clipper of the above type having a relatively short cutting head which allows for extensive and easier use of the hair clipper for hair trimming than is currently being effected with shears and comb.

A further object of the invention is to provide an improved electric hair clipper wherein the cutting head is so related to the clipper body that a clear view of the cutting operation obtains in the use thereof.

it is another object of the present invention to provide an improved electric clipper of the above type which is provided with a double ended cutting head having a convex operating surface and which is adapted for application to a head being trimmed at a perpendicular or forty-five degree angle relative thereto, permitting the clipper to be used in corner-like areas, such as behind the ear shells or the like.

Other objects of the present invention are to provide an electric hair clipper having the above objects in mind which is of simple construction, has a minimum number of parts, is easy to use, inexpensive to manufacture and efficient in operation.

For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure l is a perspective view shown alone of a preferred embodiment of my invention;

Fig. 2 is a rear elevational view thereof showing the same in operative use with a comb during the hair clipping operation; and

Fig. 3 is a side elevational view of the device illustrating the convex operating surface of the cutting head providing ready angular adjustment enabling easy manipulation thereof to adapt it to sharp turns and precise cutting in close quarters therefor.

Referring now more in detail to the drawing, indicates generally the clipper including the hollow cylindrical casing 11 within which is mounted the usual electric motor, not shown, which is powered through the 2,741,026 Patented Apr. 10, 1956 insulated cord 12, substantially as illustrated. An on and off switch 13 is mounted at the rear end of the casing 10 and controls the operation of the motor there within. 'A motor brush 14 is provided as well as a motor vent 15.

The other end of the casing 10 is tapered, as at 16, and mounts a double ended cutting head indicated generally at 17 including the yoke shaped member 18, substantially as illustrated. The cutting head 17 comprises an outer blade 19 having a convex outer face, see Fig. 3,

ice

and an inner cutting blade 20, theblades 19 and 20 being respectively provided, along the opposite edges thereof, with thepointed teeth 21 and 22 having cutting edges along the opposite converging sides thereof. ,The inner blade 20 is adjustable laterally relative to the outer blade 19, the necessary lateral movement being provided by the driveshaft of the motor which extends outwardly through the yoke 18 and mounts thereon an eccentric means, not shown, for effecting the desired lateral movement of the inner blade. The provision for such eccentric control means for a laterally movable blade is so well known in the art that details thereof appear unnecessary herein, particularly since such feature forms no part of the invention. The relative displacement between the teeth 21 and 22 elfects the cutting of the hair in cooperation with the comb 23. As shown in Fig. 2, the comb 23 moves vertically, while the clipper is moved from right to left and left to right along the comb to effect the zigzag path shown by the arrows of Fig. 2.

The length of the blade 19 is of standard size, approximately two inches, while the height of the blade is approximately one inch.

As shown in Fig. 3, due to the convex outer face of the outer blade 19, the cutting head may be tilted to an angle of appproximately nine degrees in each direction during the cutting operation. This permits a radius R of turn of approximately two inches as compared with standard clipper radii of four and one-half inches.

Thershort cutting head 17 allows for extensive and easier use of the hair clipper for hair cutting than is currently being accomplished by means of shears and comb. The clipper double ended cutting head 17 having the adaptable convex operating surface allows perpendicular or forty-five degree angle hair adjustment, the clipper being capable of working in corner-like areas, such as behind the ear shell, etc. The mounting of blades 19 and 20 within the extending arms of yoke 18 affords a blade mount simplifying clipper head construction and increasing blade cutting efficiency. This is particularly advantageous since no central blade support posts are present which would interfere with the vision of the operator at any time or in any direction of operation.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

1. In a clipper including a housing and having clipper operating means mounted thereon, a substantially U- shaped extension on said housing having its open end outwardly thereof, a first blade element having cutting teeth therein being fixedly mounted across said U-shaped extension in spaced relation to said housing, a second and cooperating blade member mounted in abutting relation to said first blade element and having cooperating cutting teeth thereon, said second blade element being connected to the clipper operating means in spaced relation to said housing for movement thereby laterally of said first blade element whereby the cutting head is positioned in spaced relation to the housing so that a clear view of the cutting operation is obtained.

2. An electric hair clipper device including a housing havingoperating means mounted thereon and connected therewith comprising, a yokeelement fixed to said housing, a fixed blade element having cutting teeth 0110p posed edges thereof connected to the outer extremities of the yoke element, a second blade element overlying said first blade element having cutting teeth cooperatively related to the cutting teeth on the first blade element and being connected for movement by said operating means laterally relative thereto in the cutting operation, said first blade element having a convex operating surface permitting tipping movement thereof relative the subject to which it is applied.

3. An electric hair clipper device comprising, a housing having operating means mounted thereon and extending therefrom, a U-shaped yoke member fixed to said housing with the open end thereof in outwardly extending relation thereto, a relatively narrow double-edged cutting blade fixed intermediate the extremities of said yoke member, said blade having a smoothly convex outer operating surface symmetrically deviating from its outer extremity at an angle of at least 9, and a relatively narrow second blade element overlying said first blade element and being connected to said operating means for movement thereby laterally of said first blade.
